Protein subunit vaccine based on SARS-CoV-2 receptor-binding domain shows promise against multiple SARS-CoV-2 variants
In a recent study published on the preprint server medRxiv*, researchers described a novel protein subunit vaccine that includes the receptor-binding domain (RBD) of the ancestral severe acute respiratory syndrome coronavirus 2 spike (S) protein (SARS-CoV-2). , dimerized with an immunoglobulin (Ig)G1 fraction, crystallizable domain (Fc). Study: Broad immunity to SARS-CoV-2 variants of concern mediated …
